2018--2020 Buick Regal - 2.0L Turbo - Advantage

2019 Buick Regal TourX 2.0 Turbo calibration...

For less than $500 you get 40+ hp, improved throttle response & gear shifts. Plus, it get's rid of the annoying auto stop. If you want the car to return back to stock with the stupid auto stop,  just arm the cruise control. 

Instructions were straight fwd...less than 20 min & you're all set. Immediately noticed the difference as soon as I turned off my street to the main road. Trifecta was prompt getting back to me on any questions I had. Very happy.   

First of all I will say I very seldom write reviews. I purchased the advantage calibration for my 2018 Buick Regal Sportback. The Buick was sporty enough from the factory but I HATED the Auto-Stop function that GM so thoughtfully forced upon me (with no way to disable it) so I was looking to the aftermarket for a solution. I visited a local performance shop and heard about the auto stop delete I could get from Trifecta. When I saw the Advantage Calibration I couldn't resist. I'm very happy with the improved performance and shifting. And for the money spent I don't think there is any other way to gain 25+hp and Torque! 

Definitely feel increase in power; car is transformed from feeling spritely to feeling like a performance car. Also appreciate that the auto stop-start is defeatable. Best of all, the tune is idiot-proof...be sure to hold the start button for 10 seconds like it says.

This product is CRAZY!  Trex stock was fun, fast (ish) and good enough for everyday use. I honestly find myself driving with the tune off most of the time because if I don't, I feel myself driving like an STI owner.  If you get this, I would highly suggest upgrading your tires and brakes.  I promise those corners will come at you A LOT faster than before.  If my next car is covered by Trifecta, I'll be buying again. 

After hearing about all the positive results from the group on Facebook I made the leap. It made the car 10x more fun to drive. Shifts are confident and throttle response is snappy. Extremely happy with the purchase!

Bought this for my TourX. Shift patterns are way better, and at speed acceleration is far more noticeable.  Definitely makes the car way more fun to drive.  Worth the price and would do it again. 

Have the tune installed for the last 5 months. Cannot comment on the fuel economy since I installed the tune within a week of getting the car and installed bigger tires. I am not sure how reliable the onboard computer is, but in mixed traffic it indicates about 25mpg in average since the tune is loaded. I like how responsive the car is and the longer gears. Makes the car overall more fun to drive. Trifecta service was great since I experienced some trouble during the first load. I like that Trifecta offers continuous support and will let you know when there is an updated file available (wondering what the current August 2020 update is about).

Didn't know what to expect...but pleasantly surprised!  While I definitely noticed a difference off the line with quicker acceleration and better throttle mapping (tune holds the gears longer but still shifts smoothly), where I really noticed the difference was at freeway speeds.  When wanting to pass another vehicle or merge onto the freeway, the car's acceleration is much, much stronger!  I could be going 50-60, pass another vehicle, and before you know it I'm going 90+.  Since the shifts are still smooth and the TourX's ride is already good, you don't even notice how quickly you've accelerated.  Highly recommend.  Super easy to install and when I had a question about installation, Trifecta was quick to get back with me and guide me in the right direction.

Consistent with other Trifecta tunes I've had, this one for my 2018 Regal TourX has transformed the driving experience. Much better throttle response overall, and especially at freeway speeds. The tune has improved the shift characteristics dramatically; lower gears are held longer during moderate acceleration around town. Once in a higher gear, a slight blip on the throttle gets a decisive response. Tip in is smooth. Much easier to modulate at all vehicle speeds. Excellent, smooth acceleration when needed. Fuel economy is very good, though I have no real reference since I switched to winter tires right after I bought the car. Even so, I think 25 or so around town and around 30 on the freeway in winter is good for a larger car like this. Very smooth and responsive overall, with much improved performance, while retaining the Buick's serene nature while cruising, that's an accomplishment. Highly recommended.

If Buick had this tune from the factory, they would still be making the Tour-x.

Could use better u tube support.
